application filed May 5, 1915. Serial No. 25,978.

To all whom it may concern v Be it known that I, GEORGE P; BRAND, a-

citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Automatic Flange-Controlling Mechanism, of which the following is a specification.

{ .This invention relates to certain new and useful improvements in flange \controlling particularly take-up ools for use m devices emplojiz rrg a mova le sheet, such for instance as in automatic musical instruments.

" edges.

The present I others to provide improved means for controlling the S5001 flanges, operable to slowly bring the. anges up against the opposite edges of the-sheet and to then retain the sheet as it is being wound and after In my construction theflanges are'normally out of contact with the edges of the sheet as it is being wound upon the spool and are-slowly brought together into contact arm with such edges, the construction being such. that the flanges. do not touch the ,edges 'of the sheet until after the latter has been given severalturns or wrappings about thespool, thereby presenting aplurality of layers of the sheet to offer. pressureof the flanges agamst such edges to prevent crushing or crumpllng of such rovide a pneumatic with a valvecontrol for automatically preventing undue pressure of the flanges against the edges of thesheet. No matter what width sheet is employed, the same pressure of the flanges is obtained and the sheet forms the controllingelement for controlling the pressure of the pneumatic, thereby causing the flanges to be controlled automatically for compensating for different widths of sheets. This device may be used with any type of centralizing mechanism to deliver the music on the take-up spool between the flanges.

--Other objects and advantages of the m- -vention. will hereinafter appear and the novel-features thereof will be particularly -:-:;ointed out in .the appended claims. early illustrated in the accompanying -"The invention is cl dIaWlIlgS,uWl11Cl1, with the numerals of reference marked thereon, form a part of this specification, and in which Figure 1 is a front elevation of suflicient invention has for its objects.

The flanges 3- of the take-up spool are movable upon the shaft i, bein outwardso as to'be out 0% contact with the edges of the note sheet.

"They are supported against downward movement by suitable means, as staples or the like 13 secured in the under side of the shelf9. The inner ends of these members 11 are pivotally connected one to the end of a lever 14, as at 15, see Fig. 4, and the other, as at.16, to a point intermediate the ends 05 an its other end to which is pivotally connected, as at 18, a rod or link 19 having at its other end a hook or any means 20 whereby it may be connected with and operated by the movable member of a pneumatic 21.

The pneumatic 21 has its fixed member 22 secured to some fixed part, as the end of the music spool box, as seen in Figs. 1 and 2, the being connected with the pneumatic to not be disposed in grooves 12 in as seen in Figs. 1
